+1 on This advice. C3 is what designates the bearing as deep groove which is a design feature for high rpm applications.

This explains why the deeper groove matters.

https://www.bearing-king.co.uk/article/why-are-your-bearings-c3

SKF explorer refers to deep groove ball bearing.C3 has nothing to do with deep groove,it is a higher than normal clearence bearing to accommodate the instant heat expansion on some applications.SKF explorer 6203 has a limited speed of 24.000 rpm so i think it will be more than ok.I've read somewhere that most today bearings that are not specify a C rating on them,they are usually C3 clearence bearings since C4 or C5 and even C2 are special clearence bearings.C3 are common and not need to be specified.

The wider clearance is a product of the deeper groove. Run what you will, I prefer to stick with what OEM runs.

Would be sweet if we could source some info that lists what bearings meet C3 clearance specs. Any idea where you read that info?

I believe I hate you...
Searched for about 3 years for a hi top. Ended up buying an entire saw just for the "hi"..
Now I can't part with the second 288 because I can't decide which one I like more.
Then this

I must be in the minority, I don't like high tops on anything 288, 372, 572 ect. In my opinion the low tops look way better and make a saw feel smaller and more nimble.

Iirc i read it on some SKF document.I'll try to find it and post it up here.As for explorer bearing,you can type SKF explorer 6202 and the firts result is a pdf from SKF which has all the info about that particular bearing.I remembered a little wrong,sorry.SKF as you will read on the document categorising the clearences as Normal,C2 is lower than normal,C3 is higher than normal etc.When a bearing not mentioning C grade,it is considering as Normal clearence.

It's ok to have a "low top" inferiority complex.

Us guys with BIG TOPS need all the BIG we can GIT
